Improving water use efficiency in a production nursery begins with having a clear understanding of the infrastructure and practices currently in place. Irrigation, Drainage and Energy Management Plans, or IDEMP's, describe the infrastructure and management practices in operation at a business, and outlines opportunities, suggestions and designs for on-farm improvements, to ensure the business remains profitable and sustainable into the future.
The potting operation is a major component of most production nursery operations. Increasing the overall efficiency of the potting process, can free up resources for use in other parts of the business, and improve plant quality. The following video describes the different potting methods used in the nursery industry.
Work Flow Efficiency
To achieve maximum efficiency within a potting operation, and to minimise production bottlenecks, the ‘work-flow’ process from potting to plant placement must be efficient. The following video highlights the areas that could be considered when making improvements to the overall productivity of the plant setting out operation.
Weeds or pest plants can have serious economic, environmental, and social impacts. Weeds reduce crop growth, compete for nutrients water and light, harbour insect pests and pathogens, damage the aesthetics of the plant, reduce the ability to apply crop amendments, and can be one of the most significant input costs to production.
Growing Media Air Filled Porosity Testing
Plant roots require air as well as water to remain healthy. The amount of air held within a growing media is referred to as Air filled porosity or AFP . Testing procedures for AFP aren't difficult and can be done at minimal cost with simple equipment built from readily available materials and a little bit of time. This video shows a process for carrying out a practical on-site air filled porosity test on growing media.
Growing Media Water Holding Capacity Testing
Knowing the amount of water held within a growing media, referred to as Water Holding Capacity (WHC) of your growing media can help you manage irrigation scheduling more effectively and ensure plants have adequate moisture.
Growing Media pH and EC Testing
Knowing the pH and Electrical Conductivity or EC of your growing media can help you to grow better and more consistent crops. Testing procedures aren't difficult and can be done at minimal cost. This video shows a process for carrying out a practical on-site pH and electrical conductivity
Growing Media Wettability Testing
The ability of a growing media to take up water effectively once it has dried out is critical to the growth of plants and the ability of the media to become wet again. This is known as wettability. Testing for wettability isn't difficult and can be done at minimal cost with some basic equipment
Best Management Practice Irrigation Layouts
An efficient irrigation system is designed to deliver the appropriate volume of water evenly, to meet all plant needs and in the time available.The irrigation system should apply water evenly across the cropping area, apply the correct volume of water often enough to meet plant demands and apply
